摘要： An emitter (12) of electromagnetic radiation is configured for modes of operation providing fields of illumination of different widths, and a photodetector (11) is configured for time-of-flight and proximity measurements by detecting electromagnetic radiation that is emitted by the emitter and reflected to the photodetector. The emitter is operated by a driver (13), which is configured for an alternation between the modes of operation. A time-of-flight measurement is performed when the field of illumination is narrow, and a proximity or ambient light measurement is performed when the field of illumination is wide.

摘要： This disclosure relates to illumination modules operable to increase the area over which an illumination source, such as a vertical-cavity surface-emitting laser or light-emitting diode, illuminates. Such illumination modules include a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimation assembly operable to collimate the light generated from the illumination source, a translation assembly operable to translate light over an area, and a mask assembly. In various implementations the illumination source may be rather small in area, thereby reducing the cost of the illumination module. Some implementations of the illumination module can be used for the acquisition of three-dimensional data in some cases, while in other cases some implementations of the illumination module can be used for other applications requiring projected light.
